Multiple CountIf function in Power Query

Anonymous — Tue, 25 Aug 2020 05:56:22 GMT

Hello everyone,

I would like to enforce a countif function in from a data source I have.

There are multiple columns containing a "Yes", "No" data. Is there a way I can enforce a countif function using Power Query?

Thanks!

Hello Anonymous

you can make a countif with Table.RowsCount and Table.SelectRows. Basically first filter the table and then count the rows.

this code would look like this

CountIf = Table.RowCount(Table.SelectRows(PreviousStep, each [A]="yes" and [B]="yes" and [C]="no"))

Here the complete example

let Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WqkwtVtKBknn5SrE60QgOXATGRlOCIOGKUIXQDY8FAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [A = _t, B = _t, C = _t]), PreviousStep = Table.TransformColumnTypes(Source,{{"A", type text}, {"B", type text}, {"C", type text}}), CountIf = Table.RowCount(Table.SelectRows(PreviousStep, each [A]="yes" and [B]="yes" and [C]="no")) in CountIf

Copy paste this code to the advanced editor in a new blank query to see how the solution works.

Hi Fowmy ,

Since the data is confidential, I have sent a modified excel file for you to have a look at it. FYI, data that I'm using comes from a Sharepoint list connected to Excel.

What I would like to achieve is a COUNTIF Function on columns. If any of these columns contains a "No", then it should count as 1.

I don't think conditional formatting column works because it doesn't seem to count the next column after that. I have thought of using excel formula but it would be easier if I can achieve this in Power Query itself.

Thanks!

Try this in a blank query and you can copy the following code in blank query and check the steps.

Hello Anonymous

you can add this formula to a new column

if List.AnyTrue(List.Transform(Record.ToList(_), each _ = "no"))=true then 1 else 0

this gives you 1 if a "no" is present in your row

here the complete code

let Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WqkwtVtKBknn5SrE60QgOXATGRlOCIOGKUIXQDY8FAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [A = _t, B = _t, C = _t]), PreviousStep = Table.TransformColumnTypes(Source,{{"A", type text}, {"B", type text}, {"C", type text}}), AddCountIf = Table.AddColumn ( PreviousStep, "CountIfNo", each if List.AnyTrue(List.Transform(Record.ToList(_), each _ = "no"))=true then 1 else 0 ) in AddCountIf

Hi there Fowmy

Your code works! Thanks a lot!

However, I would like to see if I'm able to group the columns. Example, Column 1, Column 2 and Column 3 into a new COUNTIF Column. Then Column 4, Column 5 and Column 6 into another new COUNTIF Column.

With you current code, do I need to separate each columns into separate subset code?

Please try the following code, I have added two columns as requested:

let Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WcnEMcVTSwUbF6sBl/fxhBLoMsgKIXCwA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Column1 = _t, Column2 = _t, Column3 = _t, Column4 = _t]), #"Added Custom" = Table.AddColumn(Source, "1st Two Columns", each List.Count(List.Select(Record.ToList(Record.SelectFields(_,{"Column1","Column2"})), each _ = "NO"))), #"Added Custom1" = Table.AddColumn(#"Added Custom", "2nd Two Columns", each List.Count(List.Select(Record.ToList(Record.SelectFields(_,{"Column3","Column4"})), each _ = "NO"))) in #"Added Custom1"
